We should just all stop arguing with Sticky. Hes gonna debate til hes blue in the face and 6ft under. S65 4lyfer right here.we show facts and videos, he shows his facts and videos and says ours dont mean anything. Hes never lost one argument at anything, even when hes been 100% wrong in some cases.

You haven't shown any facts and videos. The counter-argument has amounted to gains with bolt ons and youtube race videos.

A dry sumped racing version of the BMW P65, all aluminium, 90-degree V8 engine powers the M3 racecars. This has the same bore and stroke dimensions of 92mm and 75.2mm as the production power unit giving a swept volume of 3999cc. In its initial ALMS competition form, with two 30.1mm air inlet restrictors fitted, the engine generated 460bhp at 7500rpm with maximum torque of 500Nm at 5500rpm. For the engine’s 2010 configuration, BMW Motorsport quotes a peak power output of 500bhp at 8750rpm. In contrast, the production engine develops 420bhp at 8300rpm with a peak torque output of 400Nm at 3900rpm.
Castings for the P65 engines are produced at BMW’s light alloy foundry in Landshut, the same facility at which its Formula 1 engine castings were produced. The aluminium alloy cylinder block incorporates a bed plate lower section, which carries the five main bearings that support a forged steel crankshaft driven by steel connecting rods and fully skirted forged aluminium pistons. Power for the aluminium alloy, double overhead camshaft cylinder heads is taken from the nose of the crankshaft and is transmitted to the four valves per cylinder via rocker arms and steel bucket tappets.

I don't see the P65 being too much different externally than the S65. I'd imagine the internals are beefed and lightened to conform to the extremeties of racing. However, the same basic outly of the engine is the same. Essentially speaking, the dinan stroker kit or even a bolt on M3 makes more power than the actual racing engine used. I'm referencing the 460hp with restrictors here. Therefore, you can and are purchasing a racing engine. Just need to add some components and viola.

Plus what are we debating here? The N54 isn't raced competitively. It isn't an M motor. It isn't equal to an M motor. It never will be.

I don't care how much air you pump into it.

LOL so now a P65 running with an aftermarket standalone is ok but the Alpina motor in the B3 GT3 was a MAJOR redesign because of its 9.4 compression pistons and SAME everything else. Quiet laughable especially given how much is involved on both sides and given tuning potential on both motors. S65 is simply underwhelming OEM accept it especially given how well the S54 did and still does, simply an inadequate upgrade

@Sticky . If the S65 is the best thing since sliced bread, then why are you getting rid of yours after you beat all the records? By the sound of this thread you would just be downgrading with your next project.

You don't know my next project.

The reason I would sell it is because it would be time for a new project as a promotional piece for my websites. Once I'm done there is nothing else left to accomplish.

You want to be realistic. The S54 was a let down. The S54 is a gutless and torqueless wonder powering a heavy car. My E46 has every option including the competition package and weighs 3420. At the time of its release you had the 01 Cobra that was faster, 01 C5 would walk one stock for stock, S4 was right there, 01 C32 was faster, the 996 was about to enter a refresh in 2002, which it did and it was a hair bit quicker with the 3.6, etc etc and these are just <400 hp cars. The S65 has done an incredible job now that it has to fight off 500 hp cars. It will outdo a GT500 at the track, a C5 Z06 at the track, a Mustang GT 5.0 is still behind in lap times, and you're all saying it's weak?

The S65 was a godsend from BMW. Comparing the competition from back then to now, it's insane. The S65 is more impressive than the S54 because of the competition it has been able to fend off using a mere 4.0 liters or .8 more displacement than the outgoing S54. It's impressive hands down. If you don't believe me, how impressive is Audi's 4.2 in their chassis? The RS5 is brand new. How long has it taken Audi to finally develop a chassis comparable to the outgoing model? 5 years. Mercedes has built an excellent 6.2 or 6.3 whatever the hell it is. Very impressive engine as well. But, it's not as impressive as the S65 because of the displacement cap. Still an impressive engine nonethless.

We compared the Alpina to the M3 GTS, not a P65 base race car. The Alpina needed new internals, not the S65. And the S65 is faster.

Ya super underwhelming:

Mark Gillies of Car and Driver magazine says: "A car has got to be pretty spectacular to win over the curmudgeons here at 1585 Eisenhower Place, especially when familiarity sets in over the course of 40,000 miles. But our Sparkling Graphite Metallic M3 did indeed win us over.", and "Based on our experience, the current M3 is the world's all-around best car for the money, although several staffers would have preferred to trade some of the coupe's looks for the added practicality of the sedan.", and "This is the finest car on the market, period."

Some people don't understand that there's no replacement for displacement. None whatsoever. Adding turbos helps, but does not solve the problem. The ones talking here about bolt ons are either N54 owners expecting the S65 to produce the same gains or S65 owners expecting big displacement bolt on gains. It will not happen like you would like. It's exactly like what the GT3RS guys are going through. You know the only way to make more power from one of them is? You want to talk about how maxxed out their engines are? The only way to make power with the old GT3 RS 3.8 is to do the 4.0 build. An exhaust is yielding incredibly minimal numbers. There's a max of 15 rwhp to be found with bolt ons. After that there is no cam, there is no intake, nothing. It's an all out build. At least with the S65 you can go up another 20-30 rwhp with bolt ons and another 20-30 on top of that with an all out build.
